dot3OamLoopbackControlRx

Module: EFM-COMMON-MIB

OID (symbolic): EFM-COMMON-MIB::dot3OamLoopbackControlRx

OID (numeric): 1.3.6.1.2.1.9908.1.4.1.8

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: A count of the number of Loopback Control OAMPDUs transmitted on this interface.

An Loopback Control OAMPDU is indicated by a valid frame with (1) destination MAC address equal to that of the reserved MAC address for Slow Protocols (See 43B of [802.3ah]), (2) a lengthOrType field equal to the reserved type for Slow Protocols, (3) a Slow Protocols subtype equal to that of the subtype reserved for OAM, and (4) an OAMPDU code equals the OAM Loopback Control code.

Discontinuities of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of the ifCounterDiscontinuityTime.

What is dot3OamLoopbackControlRx?

A count of Loopback Control OAM PDUs received on this interface, i.e. loopback start/stop requests sent by the peer.
